PORCELAIN TILE CORPORATION, OF CHICAGO, ILLINOIS, A CORPORATION OF DELA- WARE TILED WALL OR THE LIKE A The invention relates to the productionof tiled surfaces of the general type disclosed in Patent No. 1,594,614 granted August 3,

' 1926, to George D. Haines. The construction shown in said patent comprises a foundation sheet to which enameled sheet metal tiles are individually cemented during the formation of the tiled surface.

The present invention aims to provide novel means by which each tile may be positively maintained in place upon the foundation sheet, during the operation of mounting a series of tiles thereon, whereby the cement may be applied at one operation to tiles covering a large surface area.

i attain this object by providing on each tile a marginal flange from which extends a plurality of tangs adapted to penetrate into the foundation sheet.

In the accompanying drawing:

Figure 1 is a fragmentary view in elevation of a tile structure embodying the features of my invention.

Fig. 2 is a vertical section taken through said structure along the line 22 of Fig. 1.

Fig. 3 is a perspective View of one of the enameled sheet metal tiles.

Fig. 4 is a view similar to Fig. 1 showing a modified form of tile structure.

Fig. 5 is a view in perspective of a modified form of sheet metal tile.

While the invention is susceptible of various modifications and alternative constructions, I have shown in the drawing and will herein describe in detail the preferred embodiment, but it is to be understood that I do' ferred construction, that hereinafter shown' consisting of a plurality of vertical wooden studs constituting the ordinary frame work of a wall or partition. To the studs is nailed or otherwise secured a rigid base sheet 11 of mineral or fibrous material.

In the face of the sheet 11 are sets of parallel, equi-distantgrooves 12, one set being at right angles to the other so that the grooves intersect to form squares. serve, as will become hereinafter apparent, to receive portions of the tiles and consequently constitute means for indicating the positions which are to occupied by the tiles. Obviously, therefore, any arrangement of grooves may be employed which will define geometrical figures corresponding to the tiled arrangement to be produced. The sheet 11 is relatively large so as to afford support for a large number of tiles.

With reference to Fig. 3, a tile is shown which comprises a metal plate 13 having marginal rearwardly extending flanges 14. The outer face of the tile and preferably the flanges are coated with vitreous enamel. At spaced intervals along the flanges, a plurality of tangs 15 are provided which, in the present embodiment, extend from the plate 13 substantially in the plane of the flanges 14.

In the construction of tiled wall, the sheet 11 is secured in place on the studs 10, after which the tiles are successively applied to the surface of the sheet in positions designated by the grooves 12. Preferably, rows of holels 16 (see Fig. 1) are provided in the bottoms of the grooves 12, at intervals which correspond to the spacing of the tangs on the flanges, in order to receive said tangs.

Generally, sharpened tangs are employed which may have laterally extending pro ections 17 formed thereon near the pointed end. The resulting structure constitutes what may be termed a barbed-tang which positively engages the sheet during the mounting of the tile thereon to maintain the tile in its mount- -ed position. Consequently, the tiles may be The grooves 12.

eration.

In testimony whereof, I have hereunto In the modified-form shown in Figs. 4 and aflixed my signature.

5, the sheet structure is substantially the same as that shown in Fig. 1, except that the tang receiving holes are omitted. The tan s on the tile are sharply pointed as at 18 to Facilitate penetration of the sheet thereby. As in the previous form, the rooves serve both to recelve the flanges on t e tiles and to designate the proper osition of the tiles relative to the sheet. T e workman, in using this construction, properl ositions the tile with respect to certain o t e grooves and then drives or forces the tile into position, causing the sharpened tangs to penetrate the sheet. Hence, the tiles are firmly held in place until the workman a plies the cement to the interstices between t e tiles.

It is, of course, contemplated that the workman may apply cement to the back surfaces of the tiles, as well as to the flanges and tangs, prior to mounting the tiles upon the sheet, in which case the tangs serve as a reinforcement to prevent the accidental displacement of the individual tiles from the wall. It should also be understood that means other than the series of grooves may be employed to indicate the positions in which the tiles are to be applied to the sheet.

I claim as my invention:

1. A tiled structure comprising the combination of a supporting structure, a sheet secured thereto, said sheet having in its face parallel recesses said recesses having a plurality of equidistant holes communicatin therewith, a plurality of tiles covering sai sheet, marginal flanges on said tiles extending into said recesses, and members on said flanges extending into said holes to maintain the tiles on said sheet.

2. A tiled wall comprising the combination of supporting means, a foundation sheet secured thereto, said sheet havin in its face recesses defining geometrical gures, tiles covering said sheet having flanges thereon extending into said recesses, and sharpened members on said flanges penetrating said sheet to maintain the position of said tiles.

3. A tiled wall comprising, the combination of supporting means, a foundation sheet secured thereto, said sheet having in its face a plurality of holes, and tiles covering said sheet, said tiles having a marginal flange thereon provided with barbed projections arrangedto extend into said holes.

4. -A tiled wall comprising the combination of supporting means, a foundation sheet secured thereto, said sheet having in its face a plurality of holes, and tiles covering said sheet, said tiles having a marginal flange thereon provided with barbed projections arranged to extend into said holes to maintain the tile in place until a number of said tiles 'OWEN E.
